Just getting started reloading for my 22-250. Finished my workbench and got the press bolted down arround 2am this morning. Planning on shooting Horniday Amax 52g and maybe some Barnes Varmint Grenades. Was gona go with H380 powder but after looking in the book and seeing you have to use magnum primers and quiet a heavier load to shoot slower fps than the Reloader 10x Im thinking about going with that. Any tips?
